0.75 cup all-purpose flour half teaspoon baking powder half teaspoon salt half cup broken nuts

Preheat oven to 180ºC .

Sift together dry ingredients (flour, baking powder and salt), and set aside.

Melt chocolate and shortening in a double boiler (in a pan which is over another pan of boiling water). Remove pan from heat, and beat in the sugar and eggs. Stir in the dry ingredients, and then mix in the nuts.

Spread combined ingredients in a well-greased 20 cm square pan. Bake 30 to 35 minutes, or until top has dull crust. A slight imprint will be left when top is touched lightly with finger. Cool slightly, then cut into squares.
